Interview multiple driving schools to see which one will provide the best education for the student. Do not be afraid to ask for a tour of the place and to look at the cars that they will be using to educate. You want to make sure that they are using safe and secure vehicles.
Check to see if the driving school that you are looking into is actually certified to teach in your area. Just because they say that they are a driving school does not mean that they will actually be able to give you certificate that will allow you to get your license.
